i The machine is drivenas follows: to wit:

The drive pulley 36 is mounted on one end of shaft37, the "other end of said shaft" having mounted thereon a worm 38, and said shaft 37 is mounted in bearings 39. The Worm 38 drives the worm Wheel-40,,vvhich is mounted securelyto one end ofthe shaft 16, the opposite "end of'said shaft-has securely :mounted thereon, -a"gear 41, whic'hihas'an extension huh 42,.Whioh bears against the si'deframe 1 and allows a clearance'spacefor the gears 43 and 44,} said gears heing mounted on the shafts l5'and 17, respeetivelvm In ord er to revolveythe gears 43 and 44',- I. provide. idler gears 45 and 46, which are mounted Ion stud shafts: 4j7 and 48; these gears 45.,and 46,'have ...On the; roll '13;at.points :I inount the gears 53 and 54 .the-j gear. 54xengages a gear 55. which: is mounted at one end of the. floating roll 19 and the gear 54 engages. a; gear I "-56 which is mounted on theifloatinglroll- .18.

' It will benoted that-the gears" 53.j an'd 54 are at oppositeendsiof themachine=and-the purpose of this construction is to allow the center of .theseifloatingrolls #18 and -19-to.he brought very closely together, in order.to produce a :propen curvature on the plate 22 and thnsyavoiding any tendingnto makethe plate= flats! during its passage through the rolls.,.;: v

As the gear 44 engages the floating roll 19 the gear 51 10, is revolved.

It will be seen that the roll10 and the floating rolls 18 and 19, are revolved against each other as in the ordinary Wringer, so as to draw the plate 22 throughwhile the three supporting rolls 12, "13 and 14' are revolved the same direction so as to'inipar'tjtothe floating rolls a similaifdirectional rotation. In the above description I have set forth a preferred form and means of carrying my invention into eifectnand While I have de scr1hed one specific form ofimakjing my nachmefor bending p lates,'Ij donot wish to he limited to. .the. exact iconstruction herein set forth, it being evident that I may nodify and? change. the, same to some extent without departing from the principjleof theinvention, and I .-Wish ,to be ;t1:nClQI'S. -Q d as claiming any modifications or changes which fall within the scope of this specifi'cation and claims.
